QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 445

TRIPLE OUTPUT POWER SUPPLY FOR LCD PANELS

LT1944-1

DESCRIPTION

Demonstration circuit 445 is a highly integrated three-

output converter designed as a low-cost, small size so-

lution to provide bias voltages in small portable TFT-LCD

panels. It is capable of providing 5V/30mA, 15V/2.5mA,

and –10V/1mA using the LT1944-1 dual step-up con-

verter from an input as low as 2.7V. 5V and 15V outputs

are adjustable with a change in the feedback resistors.

The third output is a negative level shifted voltage off the

main regulators.

Design files for this circuit board are available. Call

the LTC factory.

QUICK START PROCEDURE

Refer to Figure 1 for proper measurement equipment

setup and follow the procedure below:

NOTE:

When measuring the output ripple, see Figure 2

NOTE:

The 6V maximum is set by the voltage rating of

the input capacitor, the absolute maximum rating for

Vin and shutdown pins of LT1944-1 is 15V.

Attach voltmeters or oscilloscope probes between

for proper scope probe technique.

Apply a voltage source to the input of the circuit be-

tween the Vin and GND terminals. The circuit will start

up at an input voltage higher than 1.2V. Do not apply

more than 6V to the input.

each output and its closest GND terminal to monitor

the outputs. Switch on the desired channel(s) by set-

ting JP1 and JP2 to the run position.

Connect the proper load at each output.
